目的:探讨后囊缺陷性白内障手术方式,比较超声乳化技术和囊外摘除技术的安全性和效果。方法:回顾性分析后囊缺陷性白内障患者33例40眼的手术效果,囊外摘除手术组(ECCE组)10例12眼、超声乳化手术组(Phaco组)23例28眼。结果:后囊破裂+玻璃体脱出:ECCE组为3眼(25%),Phaco组为3眼(11%),两组比较有显著性差异(P<0.05)。术后矫正视力提高≥2行者:ECCE组为10眼(83%),Phaco组为26眼(93%),两组比较有显著性差异(P<0.05)。结论:对于后囊缺陷性白内障患者,超声乳化手术的安全性和效果优于囊外手术。超声乳化手术中,始终保持前房的稳定,不行水分离、在低流量、低负压、低能量下进行,正确处理后极部皮质与后囊膜的关系是手术成功的关键。

AIM:To investigate the safety and outcome of phacoemulsification and extracapsular cataract extraction (ECCE) technique for cataracts extraction in eyes with posterior capsule defect. METHODS:Totally 33 cataract cases(40 eyes) with posterior capsule defect were analyzed retrospectively. ECCE was performed in 12 eyes and phacoemulsification in 28 eyes. RESULTS:Posterior capsular rupture and vitreous prolapse:3 eyes(25%)in ECCE group and 3 eyes(11%)in phaco group(P<0.05).Postoperative visual acuities improved more than two lines:83%in ECCE group and 93%in Phaco group(P<0.05). CONCLUSION:Phacoemulsification technique is safe and has a better outcome than ECCE for cataracts in eyes with posterior polar cataract.Keeping a stable anterior chamber,no water separation and correct handling of the posterior pole cortex and posterior capsule are the key factors for successful operation during this phaco technique.
